75558888 ÷ 302 
The aim is to understand the frequency of 302 in 75558888.

On to step 1:
If we divide 7 by 302, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 302

Advancing to step 2:
When dividing 75 by 302, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 302

Let's proceed to step 3:
When dividing 755 by 302, we get 2 with a remainder of 151.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 151 after subtracting 604 from 755.
Append the next digit (5) from the dividend to 151 and continue with: 1515 / 302

On to step 4:
When dividing 1515 by 302, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 1510 from 1515, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 302

Advancing to step 5:
The number 302 fits into 58 0 times, leaving a remainder of 58.
The next digit of our result is 0. 
Result so far: 250.0
If we take 0 away from 58, we end up with 58.
Include the next digit (8) from the dividend after 58, then repeat: 588 / 302

Going ahead to step 6:
302 can be fit into 588 1 times, resulting in a remainder of 286.
The next digit of our result is 1. 
Result so far: 2501.0
If we subtract 302 from 588, we get 286.
Include the next digit (8) from the dividend after 286, then repeat: 2868 / 302

On to step 7:
The number 302 fits into 2868 9 times, leaving a remainder of 150.
The number 9 becomes the next digit in our result. 
Result so far: 25019.0
Subtract 2718 from 2868 to get 150.
Bring next digit (8) of the dividend behind the 150 and repeat the process: 1508 / 302

Going ahead to step 8:
The number 302 fits into 1508 4 times, leaving a remainder of 300.
Write down 4 as next digit of the result. 
Result so far: 250194.0
Subtract 1208 from 1508 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 9:
The number 302 fits into 3000 9 times, leaving a remainder of 282.
The number 9 becomes the next digit in our result. 
Result so far: 250194.9
The remainder is 282 after subtracting 2718 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 10:
The number 302 fits into 2820 9 times, leaving a remainder of 102.
Write down 9 as next digit of the result. 
Result so far: 250194.99
If we subtract 2718 from 2820, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 250194.99 and a remainder of 0.102.
